To all whom it may concern:

Be it known that I, JACOB TRIPLER WAIN- WRIGHT, a citizen of the UnitedStates, residing at Detroit, in the county of Wa e and State ofMichigan, have invente a new and useful Intake-Air Cleaner forInternal-Combustion-Motor Engines, of which the following is aspecification.

-By my invention I provide means that may be conveniently installed onany of the usual types of this kind of engine and for manipulating anintake flow or current of a mixture of dirt and air in a way to ejecttherefrom much of such dirt or solid particles of matter because, theyact as an abrasive to injure the interior parts of. the

engine; also, means to [utilize intake-sud,

7 removal that has not, been attained in the prior' state of the artunder such exacting requirements.

In a conventional manner, a preferable way of applying my invention isshown in Figures 1 and 2 of the accompanying drawing. Figure 1represents a sectional-elevation at BB on. Figure 2, and Figure 2represents a sectional-elevation at AA on Figure 1.

In both of these figures; identical referencenumbers identify and referto parts thatiare identical, or are duplicated.

At 3 and 4, arerepresented the sides of an enclosure or box having abottom at 5 from which it may be disconnected and rec- The succession ofarrows show the progressive stages and turns which the current is causedto take between the curved conduit walls shown at 8 and theafore-mentioned straight conduit walls shown at 6. The intake to theapparatus is shown at 9,

and the outlet is shown at 10.

It may be remarked that in Figure 2 where the intake 9 is shown, it isconvenient to locate the outlet 10 also thereat in that view andconsequently it is not shown separately in that view.

It will be perceived that Figure 2 shows that the space between conduitwalls 6 is more constricted at the top than at the bottom. This featureas it obtains between the corresponding curved conduit walls 8 causes acorresponding fluctuation (rise and fall) of the velocity of the currentand thereby creates and imposes means for causing separation and removalof dirt which are more efficient than would obtain without suchchangeable constriction, and the thus created efliciency isproportionate to the corresponding rate at which such c0nstrictionchanges. This feature of my invention is purpcsed to impose underconditions which minimize turbulence, a successional series ofrecuperations of velocity to the current and consequent correspondingrecuperations of momentum to the particles of dirt floating therein, andalternate such recuperations with progression at falling velocity, andthereby rovide means to alternately impart muc momentum to theinertia-impelled self-ejecting particles of dirt; and during suchejectmcnt, to correspondingl lessen the velocity and turbulence of t egaseous portion of the current thereat and thereby lessen the resistanceto and consequently facilitate the progress of such inertia impelledparticles of dirt through and out of the thus quieted gaseous portion ofthe current. It will'be perceived that efficiency of the device isdependent also upon thenumber of such treatments that are comprised inthe successional series through which the stream is progressed.

It will be perceived that, the combination of features thus described ismore eficient in producing desired results than, was ever attained inthe prior state of the art.

I claim:

A conduit adapted to progressively conduct a stream of dirty air througha sums sion of alternating turns respectively in contrary directions,and constructed in a way to constitute means to impose alternatedecreasing and increasing stream-velocity intervening respectivelybetween such alter-- nating turns in such progression, and constructed111 a Way to constitute means toenable self-impelled ejectment of dirtfrom the stream during such progression through turns which follow acorresponding decreasing stream-velocitya'nd precede a correspondingincreasing stream-velocity.
